>Description:
When attempting to build a releng/9.2 release, errors referencing 'freebsd45.dtd' (should be freebsd50.dtd now?) cause docs build (and ultimate the rest of the release build) to fail, e.g.

# cd /usr/src/release
# sh generate-release.sh releng/9.2 /var/9.2-p2

eventually errors out with a dtd error related to not being to able to pull in freebsd45.dtd, which leads to undefined entities and other XML-related validation errors.
>How-To-Repeat:
# cd /usr/src/release
# sh generate-release.sh releng/9.2 /var/9.2-p2
>Fix:
/usr/src/release/doc/en_US.ISO8859-1/relnotes/article.xml should reference "../../../share/xml/freebsd50.dtd" (as in base/head now?)
